After watching my captain struggle to reef our 51' cat at the mast, I wanted a safer system Furlboom. They should have told me, we can't adapt this to your boat. Instead, they stressed the advantages. The system is a complete disaster. The installer in Florida had to cut and cut so the sail would fit in the boom. Ultimately, there was 80% of my former sail. The halyard frays, stretches and the sail buckles. The lines that run back to the cockpit are mis-aligned through the spin locks, threatening to tear them out. The vang is under powered for handling the load of the sail.

Furling and unfurling the sail? It now takes 2-3 people. I wanted this to improve the safety under adverse conditions, now it's worse!

So far, no response to my request to take this mess back. My opinion, mono or cat, if you are under 40', may be OK. If over 40', work on improving what you have. This is not the way to go in a larger boat and they should not put this system on another large cat.
